SPRUCE Methylotrophic Methanogenesis in Sphagnum-dominated Peatland Soils- CH4 and CO2 Production in Laboratory Incubations

This study investigated the potential for methylotrophic methanogenesis in three Sphagnum-dominated peatland soils in northern Minnesota. Soils collected from 2014-06-01 to 2015-06-30 were amended with 13C-labeled traditional substrates (acetate and sodium bicarbonate/ H2) and methylated substrates (methanol, monomethylamine ("MMA"), dimethylsulfide ("DMS")) and monitored for 13C-CH4, 13C-CO2, and net CH4 and CO2 production in laboratory incubations. The peatlands included in the study were (1) the S1 Bog, home to the SPRUCE Experiment and located at the Marcell Experimental Forest (MEF, U.S. Forest Service), (2) Bog Lake Fen, also located at the MEF, and (3) Zim Bog. These sites have been described in detail previously (Medvedeff et al., 2015). This dataset contains one file in comma separate (*.csv) format.
